5.4 Sounders
5.4.1 Sounder Output Types
•
The system supports three different methods of connecting sounders :-
1. Connected directly to terminals on the base card.
2. Connected to addressable sounder modules on any of the signaling loops.
3. Connected to addressable 4-way sounder cards on the 485 peripheral loop.
5.4.2 Allocating Sounders
•
All sounder outputs, on-board, loop driven and peripheral bus units are programmed in the same way.
•
The only functional difference between the three types of device is that some loop driven units (depending on
type and manufacturer) can not be synchronized. It is therefore recommended that any single installations that
require multiple pulsed sounder circuits should only use the on board and the peripheral bus outputs.
•
Press ‘7’ to select the sounders option from the configure menu. The display will show which ringing pattern
numbers are assigned to what sounders.
•
Each ringing pattern maps the sounders operation relative to zones in alarm.
Immediately after a "wipe system", followed by auto learn of both loop driven and peripheral
bus devices, the system will default to :-
All ringing patterns are set to ON for all zones.
Base card sounder A set to pattern number 3
Base card sounder B set to pattern number 4
Base card sounder C set to pattern number 5
(ZXe only)
Base card sounder D set to pattern number 6
(ZXe only)
All other loop and peripheral sounders set to pattern number 1
•
On selecting the sounder option, the display will show the setting for the base card, sounder A, as follows:
SOUNDER Pattern
A 003
•
A flashing cursor over the number field on the display indicates that a new pattern number can be entered from
the keyboard.
•
To inspect or change the zonal ringing rules associated with the pattern number, press the ‘
Enter’
key. The
display will then show: -
Pattern Zone Mode
3 01 to 80 On
•
This display shows several pieces of information. To avoid ambiguity as to what can be modified, the display will
flash the item that can be changed. If this item is a number and you want to change it, then simply type the new
value over the top. If the item is not numeric, then use the "
Change
" key to make your change. For example.
